IMPROVEMENT IN SEEDlNG-MACHINES.

Specification forming part of Letters Patent No. 24,979, dated August 9, 1859.

To all whom it may concern.-

Be it known that I, JOHN ANDREWS, of Olinton, in the county of Worcester and State of Massachusetts, have invented new and useful Improvements in a Vibrating Harrow and Grain-Sower Combined; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 represents a top view of my improved vibrating harrow and grain-sower combined. Fig. 2 represents a side view of the same. Fig. 3 represents a longitudinal vertical section taken on the red line A B, and Fig. 4 a rear end view.

The same letters indicate like parts in all the 1 will now proceed to describe its construction and operation.

a a represent the side or bed pieces of the harrow and the cross-pieces on the front of the harrow.

b b represent braces. 0 represents a bent angular cam, and is placed on and near the center of the axle d. The axle d rests on bearings in the stands 6 e on the side or bed pieces a a.

ff represent wheels placed at each end of the axle d and outside of the cross or bed pieces a a. These wheels have large flat surfaces on their outer circumference to prevent their sinking into the ground. One of them is made fast, and revolves with the axle din order to enable turning the machine more easily and readily. g g g g represent longitudinal blocks of timber or joist, in which are placed barrow-teeth of the usual form. The blocks 9 g g are placed a short distance apart, parallel with each other, and between the side or bed pieces a a.

It represents a cross-bar placed near the rear end of the side or bed pieces a at, extending from one to the other, and fastened thereto.

*5 t 13 represent rods or bolts with large heads. These rods or bolts are made to pass down through the cross-bar h, through holes in the blocks g gg, and secured by means of a not on the bottom.

j represents a bar placed on and near the front end of the blocks g g g.

k k k represent rods or bolts having large heads.- These are also passed down through the barj and through holes in the blocks ggg.

1 represents a stand, from which project the guidesm m. The outer edgeof the camcpasses down between the guides on m. \Vhen the machine is put in motion and the axle d caused to revolve, then the outer edge of the cam c in its revolution is brought into contact with one of the guides on and pushes the end of the blocks ggg to oneside. Then when the reverse bent part of the cam cis brought to bear upon the other guide on the end of the blocks g g g are moved in an opposite direction, thereby giving to the barrow-teeth a zigzag motion and producing the result before mentioned.

it represents a hopper, made wider at the top than at the bottom, placed on the front and extendingthe whole width of theharrow. This has divisions or partitions made to conduct the seed toward the holes in the bottom thereof.

0 represents a slide placed underneath the the hopper n and extending the whole length thereof. The slide at is provided with cups and followers for receiving the seed and regulating the quantity to be sown.

p p 19 represent boards placed underneath the hopper, and in opposite angular direct-ions, for spreading and scattering the seed as it falls to the ground. q q represent guides on the slide at and in which works one edge of the cam 0, when the shaft or axle dis made to turn, causing the cam c to revolve and bringing the edge to act upon one of the guides q, and pushing the slide it one side in such a manner that the cups are brought directly underneath the holes, where they are tilled with seed. Then when the reverse bent part of the cam c is made to act the slide n is carried in an opposite direction. The cups being then emptied of their contents, the seed falls upon the boardspp p, and is conveyed to the ground in an even and thorough manner.

1' 4" represent wheels placed in the rear end of the side or bed pieces a a for the purpose of keeping the harrow at an even height above the ground. The depth at which the ground is required to be stirred may be regulated by the raising and lowering of the barrow-teeth.

8 represents the shaft. or pole to which the team is attached.

The harrow may be used in connection with the grain-sewer or not, as may be desired.

seed-slide, and the barrow-bars ghave a horizontal vibration and also a vertical play with the frame upon the axle 01.
